You would round the number UP - to read 39.9910 (or 39.991)
Decimal point zero four is not equal to decimal point four zero..04 = 4/100.40 = 4/10thus, .04 < .40
The digit in position 271 after the decimal point is 4.
2.8

All numbers that have a 4 before a decimal point and some non-zero digits after the decimal point lie between 4 and 5. If the "between" is inclusive, then the numbers 4 and 5 (which can be followed by a decimal point and any number of zeros) also lie there.
Decimal point zero four is not equal to decimal point four zero..04 = 4/100.40 = 4/10thus, .04 < .40
You write it as 0.004 because to the left of the decimal point is ones, to the first zero to the right of the decimal point is tenths, to the second zero to the right of the decimal point is hundredths, and so on.
The digit in position 271 after the decimal point is 4.
4
point 4
The number in the second place after the decimal point shows the value of hundredths.EXAMPLE 0.345 : The '4' represents 4/100.

A decimal point is the actual point. A decimal is the number that has a decimal point in it. For example; 28429.018
All numbers that have a 4 before a decimal point and some non-zero digits after the decimal point lie between 4 and 5. If the "between" is inclusive, then the numbers 4 and 5 (which can be followed by a decimal point and any number of zeros) also lie there.
0.4 has 4 tenths. In decimal form, each place value after the decimal point represents a power of 10. The first digit after the decimal point is tenths, so in the number 0.4, there are 4 tenths.
The percent is 4% (decimal to percent move decimal point two places right).
